Abstract

Un filtre de filtration continue d'un liquide comprend une cuve classique (1) dotée d'un arbre central (2), sur lequel est agencé au moins un élément de filtre rotatif définissant un espace intérieur destiné au liquide obtenu lors de la filtration. On a également prévu un dispositif de lavage (6) destiné à laver la matière déposée sur ledit élément de filtre, un raccordement entre ledit espace intérieur et le moyen de sortie de ladite cuve, ainsi qu'un séparateur (10) raccordé à ladite sortie, et adapté pour séparer un filtrat et un gaz. On a prévu des moyens (19, 20) à l'extérieur de ladite cuve destinés à créer une surpression dans l'espace de gaz de ladite cuve, et une souspression à l'intérieur dudit élément de filtre, correspondant au moins à la température d'évaporation du liquide filtré, afin de procéder à l'évaporation du liquide se trouvant dans ledit séparateur. Ledit séparateur (10) comporte un dispositif de refroidissement (26), destiné à refroidir le gaz séparé, ainsi qu'une sortie destinée au condensat obtenu lors du refroidissement.
